Production of heat resistant conveyor belt used rubber has three kinds: styrene butadiene rubber, ethylene propylene rubber, chloroprene rubber.

Styrene butadiene rubber (1)

Styrene butadiene rubber is the most commonly used as anti tropical materials, it compared with the ethylene propylene rubber and chloroprene rubber, styrene butadiene rubber per ton at present price is 12000 yuan, much lower than that of ethylene propylene rubber and chloroprene rubber. So the production enterprises for the production of T1 or T2 type belt conveyor. Technological properties of styrene butadiene rubber, such as mixing technology, rolling technology, curing process is good, appearance quality with respect to ethylene propylene rubber and neoprene is much better, in rolling out a little more stable size, good molding process on the belt core adhesive, curing appearance defect situation than ethylene propylene rubber, neoprene less.

Ethylene propylene rubber (2)

The use of ethylene propylene rubber as heat resistant rubber covered tropical heat resistance, better performance, is the ideal material for conveyor belt of heat, under normal circumstances, three yuan of ethylene propylene rubber can be 150 ℃ environment for long-term use, but three yuan of ethylene propylene rubber technology is poor, cover rubber adhesion is poor, not easy belt core adhesive, high this production enterprises tend to spend a lot of energy development and cover both adhesive and adhesive and the core layer. Rolling out a little more than 4mm often rough surface, is not smooth enough, and at the same time with colleagues due to the transition layer and the core layer, often in the layer between the air, if the process does not pay attention to operation and adopting some technology measures, adhesive tape is easy to produce the scars, edge appearance defect Gou, foaming etc.. The adhesive for T3 type belt conveyor.

(3) chloroprene rubber

Chloroprene rubber heat resistance than styrene butadiene rubber and ethylene propylene rubber, but has good resistance to acid and alkali, chemical fertilizer production, especially the production of SSP process of phosphate fertilizer industry, requirements for conveyor belt acid also heat, the heat is not high, only in 100 ℃, and acid and alkali resistant performance requirements are particularly high. In this work conditions, the selection of raw materials of chloroprene rubber as type T1 heat resistant conveyor belt. Chloroprene rubber, ethylene propylene rubber process performance and Ding Benjiao are different, because of the hot viscosity is relatively large, out a little taste sticky roller, rolling out a little shrinkage, curing easily and hot plate bonded by pocket, easy to produce the scars, foaming and breach. Repair is not easy to stick, to take special measures to ensure the smooth surface of the belt should be the appearance quality, less defect.
